SDC Security Door Controls 928 Series Integrated Digital Keypad, 480 PIN Codes

Product Overview

The SDC 928 EntryCheckTM is a stand alone digital keypad designed to control access of a single entry point for facilities with up to 480 users. Each user is assigned a personal identification number (PIN). Keypad entry of a valid one to six digit code activates one or both of the output relays which releases an electric door lock.

Programming Options

The 928 EntryCheckTM includes a Door Sense/Inhibit Input
feature. When programmed for "Door Sense", a door
position switch wired into the input and detects a "forced
entry" or "door ajar" condition. When programmed for "Inhibit
Input", a maintained switch or automatic timer wired into a
the input will disable the activation of the main relay.

The EntryCheckTM also has a request-to-exit input for
connection to an exit switch and/or fire access key switch for
fire/emergency access. When access is granted, the shunt
option is activated shunting alarm contacts on the door or
gate. This prevents triggering of an alarm during
authorized access.
